Abstract
Insertion of a lightguide preform (12) into a tube (14) without contacting the sides thereof is accomplished by first roughly aligning the rod in spaced axial alignment with the tube. Thereafter, the offset of the rod from the axis of the tube is measured and the amount of lateral movement of the rod from the axis is determined. Then the rod is moved laterally in accordance with the determined amount of movement to precisely align the rod with the tube. Once alignment has been achieved, the rod is inserted in the tube and the tube is collapsed thereabout. An apparatus (10) for practicing this method is disclosed.
